IGBT transistor modules are a three-terminal semiconductor device used as a switching element in power converters and variable speed drives to stop or allow power flow. IGBT transistors are controlled by a metal oxide semiconductor gate structure.
IGBT modules are widely used for switching electrical power in applications such as inverters, welding, motors, power conditioners, trains and uninterruptible power supplies.
A high-speed IGBT module is a product suitable for applications with switching frequencies between 20k and 50 kHz such as power supplies for medical equipment, welding machines, and induction heating. They include a boost chopper module and a half-bridge module.
IGBT transistor modules have different configurations such as dual, 3-level, booster, common emitter, single switch, six-pack, chopper, PIM, PIM three-phase input rectifier, twelve pack, four pack and diode.
